In The Garden: Thorny handful

I came across this plant while weeding. Looked like a maple tree as I reached to give it a yank..... those thorns stopped me. What is this plant?

 

Possible rubrus odoratus?

 

Don't think so..... this has huge thorny spikes.

 

I believe it may be Kalopanax septemlobus.

 

Wrong leaf shape, this is very reminiscent of a maple leaf.

 

I don't know the plant, but it seems to have fairly variable leaf shape, several examples on an image search look a lot like your plant.

Kalopanax septemlobus

 

Not a maple in any case, leaves aren't opposite. Nor do maples ever have thorns.

 

Yes it has thorns, yes, I said the leaves look like a maple, LOOK not ARE. The two species being discussed have a different type thorn.

 

I know nothing about this, am just chiming in with an irrelevant curiosity. I've seen two pages that give Acer pictum as a synonym for Kalopanax septemiobus (along with Kalopanax pictus). Since one of them even shows the Araliaceae fruits, that seems really strange.

Do the thorns on this Wikimedia Commons photo look so different?

Yes, I think we have a match.... apparently the leaves vary. Thank you for the assistance.
